BUILDING-BLOCK.

i To all whom it. may concern;

Be it known 'that I, IVILLIIAM C. DimisoN, a citizen of the United "States, residing at Cleveland Heights, in theflcounty of Cuyahoga and .State of Ohio, have invented a certain new and useful Improvement in Building-Blocks, of which the following is a full,"clear, :and exact description, reference beinghad to the accompanying draw- The object of this invention is to provide a building block in a form possessing great adaptabillty in use and producing very strong wall. a

.My block is tongue projecting from the' side of the head,

which parts bear such relation to each other i that the blocks may be laid up to produce walls of varying thickness and also to re ceive header courses. where desired.

. My'blocks are hollow for cheapness and lightness, but are provided with-"webs so arranged that when the blocks-are built. into a wall the webs stand in jvertical tiers, whereby the strength of the wall to resist any crushing strain is enormously increased.

The system of heads and tongues also makes a continuous.interlock in .the courses and breaks the joint betweenthem, so that the wall is tighter and much stronger against" any lateral strain than the ordinary wall.

.It is .to be understood that, while the re-' lation which the tongue ofmy block and the head'bear to each other is of importance in producing the result I do, I do not intend to limit myself to any specific dimensions. The block may be made in any length and the head and tongue of any width or height. 'As, however, my blocks are of great value inproducing a backing wall for a facing-0f pressed'brickwhic'h should be interlocked thereto by headercourses, I find it preferable to so dimension my block as to cooperate withv standard bricks. Y

The invention comprises the 'block formed to givethe characteristics above mentioned,

as herein illustrated and hereinafter more definitely explained and summarized in the claims. I I

The invention includes also the combination with sucha block of a brick wall having a cooperating header course. I

In thedrawings', Figure I is a perspective view of my block; Figs. 2 and 3 are Specification of Letters Patent. 7

formed with ahead and a Patented Dec. 7, 1999.

Ap iflication filed October 1,1908. Serial No. 455 667. v

a c REISSUED vertical end views of Walls built upof my blocks and a facing course of brick. In Fig. 2 the'back wall provided by my blocks is approximately twice the width of the standard brick, while in Fig. 3 it is mately threetimes the width.

The length of my block may be anything desired. The width of the head and the width of the tongue are preferably approxibrick, wh1le the thickness of the tongue is preferably that of an ordinary brick and the head approximately twice that thickness.

In the drawings, reference character H (with orwithout exponents) indicates .the head, T thetongue and M the mortar.

A and B indicate the top and bottom walls of the head and G and D the vertical walls thereofx Similarly, E and F are the top and- -bottom of the tongue, G the outer wall thereof and I the inner partition or web. As will be seen, the tongue projects from the middle of the side D of the head. That is, the space betweenthe surface E and the surface A is the same as the space be- I tween the bottom surface F and the bottom surface 13.. The height G of the tongue is preferably that of a standard brick. The height of the head if the mortar were disre garded would be' twice that of the tongue;v but, owingto thecourses of mortar, as hereinafter explained, the height of the head is 1 preferably more than twice the;heigl1t of the tongue by the thickness of one course of mortar. The width of the head is preferably somewhat less than the width of the tongue, the web I and the wall G being preferably the same distance apart as are the walls C and D. The width of the'head is preferably. less than half the total width of the block by an amount correspondin to one course of mortar, while the widthof the tongue is preferably one course of mortar more than half the total width.

' Taking a concrete illustration and with out limiting myself to particular dimensions, it may be observed that a-standard brick is 2% high, 4 wide and 8); long. Accordingly, for cooperation with such bricks it would be convenient to make my brick of the following dimensions; length, say 12 inches, so as to break courses with the brick face, the height of the tongue 2%, height of the head twice this plus the thick ness of a mortar'course, that is, 5 inches; the

approxi- 60 width at a head D and the web I being inch, and theto-tal.

. the 'web' I ofthe tongue below the heads H of the course below it. This i -monly 'called an 8 inch blocks..-

my blo'cks ,one' above the other alternately, the head .of one block going over the tongue facing tongue 4% inches, the space between the wall widthof the block'being 8?; inches. Bricks of such dimensions may be very conveniently laid up with standard brick of the dimensions given.-

This brings-"the wall D of the head directly over If of the'tongue directly over the'wall D of the head below it, so

necessary to keep in stock a number of shapes of blocks.

My block is much stronger in resisting downward strain.thanthe ordinary commercial-brick, while the overlapping shoulders provided by the heads and tongues give the w'alla lateral SlflffIlGSS' which is far in'excess of theiordinary wall. Anotheradvantage of a wall built of my b1ocks-'is' the non-conductivity thereof for moisture, heat, cold,

sound, etc. This is due to the overlapping of the air-containing heads and tongues of B5 my blocks, confined air being, of course,- an excellent. non-conductor.- All of the horizontal mortar joints. in my wall terminate opposite hollow spaces in the blocks, and hencexany passage ofmoisture, etc., along the moi"tar course, or through the blocks" themselves is interrupted. These features outside wall, or a partition wall. Fora par-g tition wall between different apartments, for
